Two very distinct voices of rock, frontmen of two bands who helped bridge progressive music to newer audiences of progressive listeners. both have the ability to both use the voice as a singers voices but also as an effect tool to add0, both seems to have a n unlimited high vocal range,

just listen to how Bjerre stretches his voice on the last section of Comforting Sounds, he s voice is heard in the background and adds a really mesmerizing timbre to the closing of Frengers.
